Heres how i made it.
Arduino servo door lock.
After a bit of tinkering i got a working model.
In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.
I decided to leave my servo exposed and to only build a small cardboard case to protect the arduino nano and bluetooth module.
This is a simple arduino project.
The code for password based door lock security system using arduino keypad is given below.
The servo turns back to the position it was in after some seconds.
The simply compile it then finally upload it to the atmega328 microcontroller.
When i saw this i instantly wanted my own for my door.
In this project i mede an door lock or box lock that opens when you enter your password and press.
To connect the servo motor with the arduino use digital pin d9 of arduino to output the pwm pin of the servo motor.
Arduino door lock with password.
Recently i rewatched the amazing spiderman in one scene peter parker locks and unlocks his door from his desk using a remote.
